Question

Is there an easy way to reset all the fields in a form?

I have around 100 controls in my asp.net form and there are submit and reset buttons.

How do I make all values in the fields null when user hits reset button?

I have a lot of dropdown boxes, textboxes, checkboxes.

Answer 1

Loop through all of the controls on the page, and if the control is type TextBox, set the Text property to String.Empty

protected void ClearTextBoxes(Control p1)
{
    foreach (Control ctrl in p1.Controls)
    {
        if(ctrl is TextBox)
        {
             TextBox t = ctrl as TextBox;

             if(t != null)
             {
                  t.Text = String.Empty;
             }
        }
        else
       {
           if (ctrl.Controls.Count > 0)
           {
               ClearTextBoxes(ctrl);
           }
        }
    }
}

Then to call it in your click event like this:

 ClearTextBoxes(Page);
